SPRING BED-BOTTOM.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed January 6, 1905. Serial No. 239,874-

To all whom it rmty concern:

Be it known that we, FRnDnRIoK J. VAN Own and WILLIAM C. VAN OIsn,citizens of the United States, and residents of Mayville, in the countyof Chautauqua and State of New York, have invented a new and usefulSpring Bed-Bottom, of which the following, takenin connection with theaccompanying drawings, is a full, clear, and exact description.

()ur invention relates to means for supporting cone-springs in anupright resilient position in bed or couch bottoms; and the objects ofour improvements are, first, to provide a firm and resilient base forcone-springs; second, to provide a cheap and durable hanger which bindsthe bed-bottom firmly in place on the hanger; third, to furnish a metalconmeeting-strip for the central coils of doublecone springs, which canbe easily sprung into binding connection therewith, and, fourth, toprovide a novel locking connection for the tops of the cone-springs.

In the drawings, Figure 1 is a plan view of the under side of a springbed-bottom without the hangers attached, showing our means forresiliently supporting the bottom coils. Fig. 2 is a plan view of theupper side of a lower coil as held by metal supporting-strips, thespring being broken-away. Fig. 3 shows plan and side views of a portionof the cross: strips with the rim in section. Fig. 4 is a side elevationof double-cone springs supported in our improved manner and showingmeans of attachment to the side rail of the bed on couch. Fig. 5 showssectional views of the supporting-strips at lines X X and Y Y in Fig. 2.Fig. 6 is a plan view of the top of a bed-bottom, showing ourinterlocking connection for the tops of cone-springs. Fig. 7 is a sideelevation of the middle portion of a cone-spring with the improvedconnectingstrip in section, and Fig. 8 is a similar view showing theimprovedconnecting-strip in process of insertion into the coil. Fig. 9is a detail perspective view of a portion of the improvedconnecting-strip with the single upturned'edge and the locking-coil ofthe spring shown in dotted outline. Fig. 10 is a perspective view of thelocking connection for the tops of the cone-spring, the top wires beingshown in dotted outline as embraced by the locking-clip. Fig. 11 is aside elevation of a portion of the improved hanger. Fig. 12 is a planview of the same with conesprings thereon. Fig. 13 is a sectional viewof the hanger at line Z Z in Fig. 11. Fig. 14 is a side elevation of ahanger, showing a modification of our bed-bottom, which shows asingle-cone spring supported directly upon the hanger.

Similar numerals refer to corresponding. parts in the several views.

The numeral 10 indicates a double-cone spring, and the numeral 11 thesingle-cone spring.

The numeral 12 indicates the central coils of the double-cone spring.

The bottom coils of springs 10 are securely held and supported by foldedsheet-metal strips 13 on opposite sides of each row of springs. Metalstrips 13 are placed on opposite sides of the row ofsprings with theiropen sides facing each other. The bottom coil of each spring is insertedinto the open sides of the folded strips and the sheet metal is bentdown over the wire, as shown at 1 1 in Figs. 2, 4, and 5, holding thesprings securely in place. The lower fold of strip 13 is usually made alittle wider than the upper to give a suflicient support for the spring.Metal strips 13 thus form a light, springy, and durable means ofconnecting the bottoms of the springs and holds them in place,supporting the springs so that the bottom cannot tip to either of thestrip-supported sides.

The ends of strips 13 are attached to the rimwire of edge strip 16 inthe following manner: A tongue 15 is cut from the end of the strip 13and bent around the rim-wire or edge strip 16, as shown in Fig. 3. It isobvious that the folded strip 13 can be used as a rim or edge stripinstead of the usual rim-wire, since it can be extended down the side ofthe bed and turned around the lower coil of the cornerspring and thenceextended across the ends, as shown at 17, and the end springs may havethe additional support of this end strip. This cheapens and simplifiesthe construction over a regular rim-wire.

The use of strips 13 on opposite sides of the lower coil of a row ofdouble-cone springs forms a strong support for the same; but we findthat open and highly resilient conesprings, such as are used in couchand seat work,are improved by placing strips of wovenwire webbing 18lengthwise between the supporting-strips 13,attaching the webbing-strips18 at their ends to the rim-wire or folded strip,

and stretching them sufiiciently to give ,a spring tension as theysupport the bottoms of the springs. Other webbing might be used in placeof woven wire; but we find that the woven wire gives an added resiliencyto the spring on account of the elasticity of the same. It alsoovercomes all noise from the coils of the springs striking upon themetal supports and hangers, and it also keeps the center of the coilfrom bending below the level of the base, as it will sometimes do whennot supported. For large springs the strips 18 may be stiffened andstrengthened by inserting edge wires 19 in the outer edge coils of theWebbing.

We provide a cheap hanger or cross-slat 20 for supporting the bed uponthe bed-rail 21. Hanger 20 is composed of a folded sheet-metal centralpart 22, which is placed in the bed with the cylindrical or folded sideuppermost, thus forming a strong and rigid support. Hooked ends 23 areattached to the ends of central portions 22 by suitable rivet and mayhook over the sides of the bed-rail 21 or may be attached thereto by asuitable screw or nail, as shown at 2 1 in Fig. 1.

It is found that cone-springs have greater resiliency and work better ifthey are held firmly in position against sidewise 'movements.Consequently a binding-loop 25 is supplied in the upper edge of hanger20, through which cross binding-wires 26 are inserted, whichbinding-wires pass through the loops 25 and over the bottom coils orbindingstrips 13, thus binding the springs so rigidly in place that alltheir resiliency may be reproduced. The loop 25 may be made by means ofa strip cut from the sheet metal 22 and bent upward, as shown at 25' inFig. 11, or it may be formed bya slot cut in the sheet metal and thewire 27 extended through the hanger with upward bends at each of theslots, as shown in Figs. 11 and 12.

It is apparent that if a sufiicient number of cross-hangers 20 weresupplied for each row of springs the lower coils of single-cone springs11 could be attached directly to the top of the hanger and thatbinding-wire 26 would hold the bottom of the single cone firmly inposition on the hanger. If a suitable top connection were supplied, thiswould form a modification of our spring construction which might servethe purpose. It does not, however, form as resilient and satisfactory aspring as our preferred construction.

In former Letters Patent, No. 641,660, a locking connecting-strip wasshown for holding the central coils of double-cone springs in place.This strip served its purpose well, but is slow and hard of insertion,each spring having to be turned onto the strip with its double upturnedlocking-flanges. Our improved strip 28 is formed with a single upturnedlocking-flange 29, which is given a slight incline toward the outer edgeof the strip, so that the opposite straight edge of the strip can beinserted between the coils, as shown in Fig. 8, and the inclinedupturned edge 29 presses the coils apart until it slips within the coil,locking the same around it and bracing against the inner side of thecoil, the straight edge 30 pressing against one side of the coil andboth ends of the upturned edge 29 locking against the opposite innerside, so that it cannot be removed without turning the spring off fromit, but which allows of its being pressed into place almostinstantaneous'ly in the making of the spring. This simplifies theconstruction, does just as good work as the. former construction, andsaves considerable in the 'cost of inserting the locking-strips. Theouter ends of strip 28 may be attached to the bed-rail, as shown at 24in Fig. 4.

()ur new interlock or top connection for the cone-springs is composed ofa metal clip 31, which embraces the adjacent top coils of the springs 10or11, which cliphas a slot 32 crosswise of its central portion. Across-wire 33 is provided with return-bends 34, which are inserted inslots 32 of clips 31. A wire 35 crosses wire 33 at right angles, beinginserted within bends 34 of wires 33 and locking the ends of clips 31,thus forming a tie and looking all the parts.

The outer ends of wires 33 and 35 are attached to the rim-wire, as shownin Fig. 6. Suitable clips 36 may be placed at intervening points betweenthe top wires of the cone-springs and between the rim-wire and the topwires of the outer row. It is apparent that the'interlocking clip 31,which locks against wires 33 and 35, can be worked either side up, thecrosswire 35 passing over the tops of the conesprings, as shown in Fig.10, or beneath the outer coil, as shown in Fig. 4, as seems mostdesirable.
